n imp nt obje t is the prov sion of a tail-gate structure in which the tail-gate isremovably p o ed at i s op or bottom a the case may be n equipped with lever actuated means. operable, from the frontof the vehicle whereby to release the bottom pivotal connection and permit the, gate to swing gravitationally into open position for l ping a oad wh n t e dy i tilted- Another object is the provision of a taiL ga structure o arr ged tha the ga when swung upon its lower edge, may be used as a shoveling board inasmuch as it will then form a continuation of; the bottom of the body.

A further object is the provision of a structure of this character in- Which; the tail-gate i self embodies, side retaining elements which normally fit within and against the sides, of, the body, when the gate is in vertical position, and which further serve as the. sides of the shoveling board when the gate is extended to form a continuation of the bottom. Still another feature is a detailed endgate construction in which the upper and lower h riz ntal bar em s are f rmed integral, as by forging, with the upper and lower trunnions -which may be selectively held, depending upon whether the gate is to be swung from its top or bottom edge.

The invention further contemplates the provision of various detailed improvements in the specific construction, location, are rangement and cooperative relation of the parts, particularly adjustable lever means for forcing the end gate into absolutely closed position and for maintaining it closed without the employment of any assisting springs or. their equivalent.

An additional object is the provision of a mec n sm ft i c ra ter ich il o sp o its ma y ad ntages, be s mpl and inexp sive to manufacture, sy o operat posi ive in ac ion, eifie ent a d ur le n ser i and a general mp ov men in the art- With the above and o her objects and vantages in View, the in e t on consi ts n, h coinbina ienand arrangement of Pa s to b he ei after mo e lly de i ed a d laimed and il ustra ed ,in the accompanying drawings in which: 7

Figure '1 is a sect-ion on the line 7-7 of Figure 1.

Figure 8 is a detail section on the line 88 of Figure 3.

Referring more particularly to the drawings, I have showna truck body 10 here represented as constructed of suitable angle bars 11 which extend longitudinally, and a forward transverse angle bar .12 reinforced by braces 13-, all the angle bars having secured thereto the sides 1 L and forward end 15 which have intnrned edges or f ng 16 riveted 1 ot erwise secured to the bottom 18 and beneath the same. In the present instance the body is shown as mounted on bolsters 19 supported by sills 20 Any bracket means desired may be provided for holding the body down onto the frame. 'Secured on the sides 14 at the rear ends there of, are angular brackets 21 bolted down. onto the rearmost bolster as by bolts22. Angular rein-for i g brack ts 2 are p ovided at t e upper rear corners of the sides, which bracln ets extend: outwardly of and are secured to the brackets 21 by rivets or bolts 2a which also pass through the upper ends of inclined braces 25 bolted at. 26 onto the rear bolster 19. The securing members 24 also operate to hold elements 27 for a purpose to be dedo define recesses scribed. The rear ends of the sides 14 are formed with laterally extending flanges 28 which engage against the rear edges of the brackets 21. J

Secured on the rear face of the rearmost bolster 19, are brackets 29 formed with notches 30 which define ears 31 therebelow. Secured upon the rear end portions of the longitudinal angle bars 11 are rearwardly extending strips 32 upon the tops of which are secured other strips 33 which have their rear ends upwardly offset, as indicated at 34, The projecting rear ends of these strips are formed with ver tic-ally alining holes 36 adapted for the reception of retaining pins 37 for a purpose to be described, which pins are preferably connected with chains or other flexible members 38 suitably secured to the body at any desired points and which are for the purpose of preventing loss of the pins.

lilhe end gate is designated broadly by the numeral 39 and includes upper and lower angle bars 40 and 41, respectively, to which is riveted or otherwise secured a metal sheet 42 upon the ends of which are secured angle bars 43 adapted to [it between the sides 14 of the body. The angle bar 41 has its ends con verged to define trunnions 44 integral therewith, which trunnions are removably and rotatably engaged within the notches 30. The upper angle bar 40 is forged at its ends to define integral trunnions 45 of hook-shape which are normally engaged within the recesses 35 and retained by the pins 37. The trunnions 44 and 45 both serve as pivotal supports for the end gate or a double hanging therefor and the construction and arrangement is such that the end gate may be permitted to swing either from the upper trunnions, when dumping a load, or upon the lower trunnions when the end gate is arranged to define a shoveling board. A more detailed explanation of thisfeature will be given. I have also shown reinforcing strips 46 which are secured to the angle bar 41 and to the plate or sheet 42. It is to be observed that the rear ends of the longitudinal bars 11 terminate short of the rear ends of the sides 14 so as to accommodate the angle bars 43 when the end gate is in closed position.

For holdingthe end gate in its extended position, I provide chains or other flexible members 47 connected with the above de scribed elements 27 and with bolts or rivets 48 on the end gate.

The pins 37 normally hold the upper edge of the gate in position. For holding the lower edge, I provide a rock-shaft 49 journal-ed through the ears 31 and formed at its ends with crank arms 50 and 51 which extend rearwardly of and in engagement with the trunnions 44. The crank arm 5]. has a lateral extension 52 on which is pivotally engaged one end of a rod 53 which extends forwardly along one side of the body and which has its forward end threaded and passed through a bracket 54-, pivoted at 55 on a lever 56, which is in turn pivoted at 57 upon a bracket 58 secured to the body. On the threaded end of the rod 53 are adjusting nuts 59 for the purpose of regulating the parts so as to insure tight closing of the end gate when the lever 56 is properly operated. The bracket '58 carries a retaining bracket 60 within which the lever 56 is engaged and which operates to prevent accidental displacement of the lever.

Assuming that the end gate is in its closed position, as shown in Figure 1, it is obvious that to use it as a shoveling board it is merely necessary to remove the pins 37 and permit the gate to swing down upon the trunnions 44 until it assumes a horizontal position forming a continuation of the bottom of the body. The chains 47 support the weight and the lower angle bar 41 abuts against the lowermost bolster 19 and rear edge of the bottom to prevent any space or gap.

Assuming that the end gate is in closed position and it is desired to dump a load from the body, the body is tilted in the usual manner, as shown in Figure 3, and the lever 56 is swung upwardly and rearwardly which results in turning the rock shaft 49 so that the crank arms 50 and 51 will be in nonobstructing relation to the trunnions 44, whereupon the gate will swing on the upper trunnions 45, the lower trunnions 44 riding out of the notches 30, Reclosing of the end gate is efiected by swinging the lever 56 forwardly. It will be observed that the pivot point 55 is past center with respect to the pivot 57 so that the strain of a load against the gate will operate to make the holding action still more secure. The nuts 59 permit shortening of the roc 53 to insure tight closing of the gate at all times.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. In a truck body open at its rear end, brackets mounted at the top of the rear end and projecting rearwardly therebeyond, notched brackets at the bottom of the rear end of the body projecting rearwardly therebeyond, an end gate provided at its top and bottom with trunnions removably engaged within said respective brackets, bearings at the rear end of the body below the open end thereof, a rock shaft journaled through said bearings and having late-rally extending end portions engageable with the lower trunnions for retaining the same normally Within the notched brackets, one of said lateral extensions being longer than the other-and terminating in a horizontally extending portion, and means connected With said horizontal extending portion for rocking the rock shaft.

2. In a truck body having an open rear end, an end gate pivotally mounted at its upper corners at the rear end of the body, a rock shaftjournaled at the rear end of the body and operating normally to hold the end gate in one position, and means for rocking the rock shaft comprising a bracket structure mounted on one side of the body, a lever pivoted on said bracket, a reach rod pivotally and adjustably connected with an intermediate point on the lever, said rock shaft. having one end formed as a crank with a lateral extension, abearing member carried by said reach rod and pivotally engaged upon said lateral extension, and guide means on said bracket for the lever, said lever being 'movable past center when the end gate is in closed position, the lever being then in engagement with one end of the guide means whereby the latter will serve as a stop.

In testimony whereof I hereto .afin; my signature.
